Letters'Patent No. 112,944, dated Maroh21, 1871.

IMPRVEMENT HN APPARATUS FOR vMANUFA.2"i'UP.H\lG1 WIRE.

The Schedule referred to in these Lettera Patent ,and making para nf the nameh Figure 2 is an elevation of the furnace and machinery required for the purpose intended;

My plan of operation is' to take coils` of rods of any desired diameter, and place them in a furnace tobe heated to a degree requisite for reducing them by rolling; when the desired heat is obtained, to place a coil upon a drum in the chamber of the furnace, and removed from the body of the lire, as shown at C, fig, 1 the end of the coil is then passed through the opening at D to the rolls E, the rotation of the latterdrawng or unwinding the coil from the drum While they reduce the rod in diameter as desired. The object in placing the druln (l inthe chamber is to keep itas much as possible from the body of the tire, in which the coil 'is heated, and from which itis transferred to drum C to bed'elivered to the rolls.

When coils of largesize rods are heated I transfer them direct from the furnace to the drum or reel F in the outside, and between the furnace and the rolls E, to be unwound and reduced by the rolls, as above described,

Letter A, fig. 2, shows the furnace with circular covers to openings in the` top B, for the introduction ot' the ooiito be heated,` t v I do not. limit myself to this mode of introducing the coil to the heat of the furnace, as other equallyconvenient Ways may bo employed.

0 is the drum within the furnace, to which the heated coil'is transferred when desired, WhileD is the opening through which the end of the coil is passed to the rolls E.

F is the drum cn the outside ofy the furnace, and placed in front-of the rolls E, to be used in the same manner or purpose as .the drum 0,'to receive and deliver the heated coil to the rolls E whenever it may be deemed best to transfer coils of certain size direct from the furnace to close proximity to the rolls.

The pipes ,G are for the purpose of keeping the coil to be-heated from resting on the coal, and lled with running Water to keep them from burning.

. The advantage derived by the employment of the drums consists in delivering the coil to the rolls as fast as the drawing requires, free from being tangled, twisted, or in knots, while the mass of the coil retains' its heat much longer than it would otherwise. At the same time a less rate 0f' speed of the rolls will be requisite, whereby the Wear and tear experienced in all attempts to reduce rods to a small diameter by rolls driven at a great speed will be obviated.

What .I claim, and desire to secure by Letters Patent, is'- h l'i combination with a drum or reel Within the furnace, and the rolls, the drum or reel outside of the furnace between the latter' and lthe rolls, substantially as described, and for the purpose set forth.
